TH15939A - PROCESS AND APPARATUS FOR IMPREGNATION AND EXPANSION OF TOBACCO - Google Patents

Abstract

Feed the tobacco leaves into the barrel (4) on the turntable (2). Four consecutive stations At the second station, tobacco leaves are compressed (with piston 13), at the third station, passages of tobacco leaves are taken to a pressure vessel (14), giving carbon dioxide gas. It flows through the period of the tobacco leaves, cools the tobacco leaves, closes the outlet (32), and increases the gas pressure to cause the humidification. The initial cooling was in a way that carbonized Controlled amounts of oxides form a liquid on the vial and release the pressure. And gas expansion and Evaporated liquid carbon dioxide, cooled the saturated tobacco leaves at the fourth station, released the tobacco leaves. And after that Use heat to expand.

Claims (1)

1. The process for tobacco leaf expansion consists of a process of (a) exposure to carbon dioxide from approximately 2758 kF to approximately 7287 kF and at the temperature at which gasdarbondioxide is at Or near the saturation state (b) allow tobacco leaves to remain exposed to carbon dioxide for a time It is sufficient to saturate the tobacco leaves with carbon dioxide (c) release pressure (d), after which the tobacco leaves are in an expanded state, and (e) prior to step (a) compress the tobacco leaves to a density of The pile is higher than 160.20 kg / m and eliminates the end tags:
